Deepak Nibade d0a1f30e66 gpu: nvgpu: allocate object context for specific GR instance
Add new API nvgpu_get_gpu_instance_id_from_cdev() that returns GPU
instance id from nvgpu_cdev pointer.

Store cdev pointer in channel private data channel_priv and ctrl node
private data gk20a_ctrl_priv.

Update below functions to pass cdev pointer :
__gk20a_channel_open()
gk20a_channel_open_ioctl()

In gk20a_channel_ioctl(), extract gpu instance id using cdev pointer
stored in channel_priv and new API nvgpu_get_gpu_instance_id_from_cdev().
Extract GR instance id using nvgpu_grmgr_get_gr_instance_id()

Invoke context creation API inside nvgpu_gr_exec_with_err_for_instance()
so that context is created with correct GR instance id.

Jira NVGPU-5648
